Severe Weather and Weekly Outlook for MS/LA/AL 4/7/24

After a beautiful weekend, we’ll be back into our cycle of possible severe weather come this Wednesday. With it comes a lot of rain, some hail, and some gusty winds.

To start us off, let’s look at the upper-levels. A stout low pressure system over the northern plains is extending much further south and stalling. Another low pressure system from the desert southwest is developing and moving east, however it will remain over the southern US which will affect its behavior.

With the low in the northern plains stalling over eastern Canada, this will cause the southern low to slow down as it reaches Texas and Louisiana. A broad line of storms will develop with plenty of Gulf moisture inflow over Texas, Louisiana, and Arkansas. This will start the first line of storms on Monday which will reach as far as southeastern Louisiana and northeastern Mississippi. Isolated and scattered thunderstorms will be possible across Mississippi on Monday.

Come Tuesday, the line of storms will become more organized with the warm sector developing out of the northwestern Gulf. While this won’t have a big effect of heavy rain on southern Mississippi, areas in north Louisiana, Arkansas, north Mississippi and Tennessee will see quite a bit.

Come Wednesday is when the low begins to organize and move into the southeast. With this, a stout line of storms will develop over Louisiana and Arkansas and make their way east into Mississippi and Alabama. Precipitable water amounts are quite high with this system meaning that rainfall amounts during the day will be at least 1.5 inches and could reach up to 3 inches in some areas of south and central Mississippi and southeastern Louisiana. Areas in northern Mississippi could reach upwards of 5 inches of rain by Thursday.

Other concerns with this storm system would be gusty winds and hail. Hail the size of golf balls will be possible with a slight dry sector in the mid levels helping to develop it. Strong winds will also be possible with plenty of mixing in the atmosphere as the storm passes. The tornado threat looks fairly low, but it doesn’t mean that one won’t pop up during this event. This looks to affect most of the southeast from early Tuesday morning to early Thursday morning as it moves into Alabama. We will keep you updated as the model guidance improves and the Storm Prediction Center is able to hone in on the severe weather threat.

The rest of the week looks to be quite pleasant! Temperatures will be just above average with a few clouds in the sky as we go into the weekend, so expect another good weekend to be outside.
